SASH-FASTENER.

SPECIFICATION forming part of Letters Patent No. 418,323, dated December31, 1889..

Application filed October 24, 1889. Serial No. 328,007. (No model.)

the outside of the window.

It consists in a spring bolt (or bolts) mounted in the sides of thewindow-frame and caused to engage with a toothed bar on the window-sash,combined with the features of novelty hereinafter claimed.

In the accompanying drawings, Figure 1 represents an inside elevation ofa portion of an upper and lower window sash, frame, and j amb fittedwith my improved locking device; Fig. 2, a front view of that portion ofthe device mounted in the side of the window frame and jarnb looking tothe right of Fig. 1; Fig. 3, a sectional plan taken on line 3 3 in Fig.1, broken away; Figs. 4 and 5, transverse sectional views through theupper and lower sashes and port-ions of the device, taken on lines 4 4and 5 5, respectively, in Figs. 3, broken away; Fig. 6, a rear view ofthat portion of the device appearing to the right in Fig. 3; Figs. 7, 8,and 9, sectional elevation, front and rear views, respectively, showinga modification of the spring-bolts seen in Figs. 4 and 5; Fig. 10, amodified form of the toothed bar seen in Figs. 1 and 5, and Fig. 11 asectional plan showing a modification of the parts of the device seeninFig. 3.

Like letters of reference denote like parts in the respective figures.

a a represent the upper and lower sashes, respectively, b thewindow-frame, and c the jamb, all constructed and arranged in theordinary and well-known manner.

In the side of the window-frame b, immediately opposite to the ends ofthe meetingbars d d of the upper and lower sashes a a when these areclosed, is fixed a horizontal face-plate or bracket e, through which areformed openings f f, the opening f facing the upper sash a and theopening f facing the lower sash a. Through the openings ff are caused toslide bolts 9 g, the outer end or nose of the bolt g being preferablysquare-shaped and that of the bolt g beveled for engaging respectivelyin a square-toothed bar it, fixed vertically along the side edge of theupper sash a, and in a bevel-toothed bar h, fixed along the side edge ofthe lower sash a, the two bars h h being so arranged that when thesashes a a are closed, as shown in Fig. 1, the bolt 9 will be oppositeto and in engagement with the bottom notch of the upper-sash bar h andthe bolt g with the top notch of the lower-sash bar h. The bolts 9 g areoperated by a lever '6, preferably of the third kind, which is locatedbehind the plate 6,

within a space formed therefor in the window-frame b 0, its free-endportion passing through a slot 9 in the shank of the bolt c, and througha hole 9 in the shank of the bolt g, (see Figs. 4 and 5,) the slot gbeing open in front, so that while on a backward movement of the levert' a corresponding and simultaneous Withdrawal of the bolts g g in theiropenings f f will be thereby caused, an independent backward movement ofthe bolt g is permitted by the slot g without affecting the bolt ashereinafter mentioned. The other end of the lever t' is fulcrumed at jto the back of the circular plate is, which is fixed on the face of thejamb o and formed with a central circular passage 70, within which isfitted, so as to be capable of being moved longitudinally and partiallyrotated, a pusher-button Z, having its outer end projecting beyond thefront of the plate 70 within reach from the inside of the window and itsrear end projecting beyond the back of the plate 7%), where it isswiveled (or otherwise adjustably secured) by a pin m to theoperating-lever 2' at a suitable distance from the fulcrum j.

From the back of the plate 70 project two opposite lugs at, havingdepending studs n, which respectively engage in two oppositelyinclinedrecesses 0, formed circumferentially on the rear end portion of thepusher-button Z, so that when the latter is turned in one direction thenarrow ends of the recesses 0 are brought against the studs n and thepusherbutton Z thereby locked or prevented from being pushed inward fromthe front of the plate 7c, and when the pusher-button Z is turned in theopposite direction the wide ends of the recesses 0 are brought oppositeto the studs 02 and the pusher-button Z thereby allowed to be pushedinward to its fullest extent, as

hereinafter more particularly referred to.

The bolts g g are normally held outward, or so that their noses engage,respectively, with the toothed bars h h when the sashes a a are closedor partially open, or against the side edges of the sashes at othertimes, as the case may be, by a spring 19, which is preferably fulcrumedat one end to the plate or bracket 6, its free end pressing partly uponthe back of the lever 1' and partly upon the rear edge of the bolt 9, asshown in Figs. 2 and 3; or in lieu of the spring 1), arranged asdescribed, the shank of each bolt 9 (see Figs. 7, 8, and 9) may slidethrough a box q, formed on the back of the plate 0", (corresponding tothe plate 6 of Figs. 3, 4, and 5,) a spiral spring .9 being placedaround the shank between a shoulder on the outer end portion of the boltg and the inner closed end of the box q, in which case the lever 2', inpassing through the slot t in the shank of the bolt 9*, acts as a stopto the outward projection of the latter by the spring .9, the length ofthe slott at the same time allowin of the independent backward movementof the bolt 9, as in Fig. 5.

In operation, assuming the window to be closed and locked by the bolts gg, and it being desired to open the upper and lower sashes a a to asmall extent for the purpose of ventilation, a person inside the room,after partially rotating the pusher-bution Z into the unlocked positionwith relation to the studs 11 on the back of the plate 75, forces inwardthe pusher-button Z, which throws back the lever i on its fulcrum j intothe position indicated bydotted lines in Fig. 3, and thereby Withdrawsthe bolts g g clear of the toothed bars h h, which leaves the sashes a afree to be lowered and raised, respectively, to the desired extent, or,say, a distance equal to that between the top and bottom notches of thebars h h, when, 011 releasing the pusher-button Z, the spring 19 returnsthe lever Z and bolts g g to their normal position, or so that thelatter engage with the said notches of the bars h h of the upper andlower sashes a a, which are thereby locked and cannot be opened fartherfrom the outside of the window, nor until the bolts g g are againwithdrawn from the bars h h, as before. Although the lowersash a cannotbe further raised from the outside of the window Without unlocking thebolt g, it may be entirely or partially closed without unlocking, owingto the bevel shape of the toothed bar h, which on the descent of thesash a forces back the bolt g without affecting the bolt 9 of the uppersash a.

In applying my invention to a railroad-carwindow sash the beveled topand bottom notches a o of the bar 712 (see Fig. 10) are formed withsquare shoulders or offsets w, so as to form lock-stops to the bolt 9when the sash is fully opened or closed.

For rendering the device practically inaccessible from the outside ofthe window, the plate R (see Fig. 11) may be fixed to the face of theupright Wainscot 51; within the room, the shape of the lever "Z beingmodified accordingly, in which case the recesses 0 and studs 71,previously described, for locking and unlocking the pusher-button Z aredispensed with and the lever 2' acted upon directly by the pusher-buttonZ.

I claim as my invention- 1. In a locking device for window-sashes, thecombination of the bolts 9 g, projected through openings ff in the sideof the window-frame b by a spring 19 and adj ustably secured 'to a lever2', located within the windowframe Z) c and fulcrumed at j to a plateit, fixed to the face of the jamb c, and a pusherbutton Z, projectingthrough the plate 7c and ad j ustably secured to-the lever i, withtoothed bars or racksh h, fixed to the upper and lower sashes a a,respectively, substantially as shown, and for the purpose described.

2. In a locking device for window-sashes, the combination of the plate6, fixed to the side of the window-frame b and having openings f f,bolts 9 g, projected through the said openings by a spring p andadjustably secured to a lever 'Z, located within the win- (low-frame b cand fulcrumed at j to a plate k, fixed to the face of the jamb c, and apusher-button Z,projectingthrough the plate and adj ustably secured tothe lever 2', with toothed bars or racks h'h', fixed to the upper andlower sashes a a, respectively, substantially as shown, and for thepurpose described.

3. In a locking device for a window-sash,

the combination of a lever t', located within the window-frame b c andfulcrumed at j to a plate 7t, formed with projecting studs '27, andfixed to the face of the jamb c, and a pusher-button Z, projectingthrough the plate k and adjustably secured to the lever-2', saidpusher-button Z having circumferential recesses o, substantially asshown, and for the purpose described.

In testimony whereof I have affixed my signature, in presence of twowitnesses, this 19th day of October, 1889.
